Description

The invention relates to an assembly for a system which is intended for installation in a vehicle and which is suitable for carrying the system.

Systems that are intended for installation in a vehicle, for example vehicle air conditioning systems, are known from the prior art and have pipe or cable feed lines. When handling such systems, particularly during the manufacture and installation of such systems in a vehicle, direct or indirect gripping of the system on the pipe or cable supply lines is disadvantageous, since in this way loads are transferred directly to the lines when being carried via the components . Handle points that are formed, for example, on a housing of the system increase the installation space required. Furthermore, when positioning the components, a compromise must be found between an optimal arrangement for fastening the pipe elements or cables and an optimal position of the handle points for carrying the system.

In addition, accumulators in the form of starter batteries for motor vehicles are known from the prior art, which have one or two retractable carrying handles on the accumulator housing. When the battery is installed in the vehicle, the handles are in a lowered position with little installation space requirement, from which they are pulled upwards into a transport position to carry the battery. Such accumulators are, for example, in the DE 36 29 341 A1 as well as the generic ones DE 1 596 229 A described.

The object of the invention is to create an assembly for a system which is intended for installation in a vehicle, which advantageously enables the system to be handled and whereby the system requires minimal installation space.

This object is achieved according to the invention by an assembly according to claim 1, which comprises a system with a housing and at least one first coupling interface and at least one transport handle for carrying the system, the transport handle having a second coupling interface and via the connection of the two coupling interfaces to the system can be attached. A securing part is provided, which is arranged in a securing position in such a way that the coupling interfaces are prevented from becoming loose. In addition, an unlocking body is provided, via which the securing part can be moved into the unlocked position.

Since only one coupling interface is provided on the system, the system only requires very little installation space. The system therefore requires minimal installation space when the transport handle is decoupled. The coupling interfaces can be attached to the system at the optimal locations for transporting the system without affecting other functions and properties of the system. The unlocking body enables the transport handle to be uncoupled in a simple manner.

Preferably, the coupling interfaces can have fastening means which can be detached from one another and which form a positive connection. In this way, for example, repeated non-destructive coupling and decoupling of the system and the transport handle is made possible.

For example, the first coupling interface can be formed by a fastening receptacle on the housing of the system, into which the transport handle can be accommodated.

The securing part is preferably arranged on the transport handle. The coupling interface or fastening receptacle can thus be designed to be simple on the housing side.

For example, the securing part can be a prestressed locking hook. In this way, unwanted loosening of the securing part can be prevented.

The unlocking body is provided in particular on the transport handle.

It is also possible for an ejection mechanism to be provided, which enables the coupling interfaces of the transport handle and the system to be released. The ejection mechanism, for example, moves the coupling interface of the transport handle completely or partially out of the fastening receptacle of the first coupling interface.

A lower load on the individual connections, in particular on torque, can be achieved by the transport handle having at least two spaced-apart coupling interfaces, which can be connected to the system at different positions.

The distance between the coupling interfaces preferably corresponds to at least half the length of the transport handle.

A simple positioning of the handle on the first coupling interface is made possible by providing a first pair of first and second coupling interfaces, which have a rotary can form a firm, positive connection, the coupling interfaces being particularly polygonal.

Preferably, a second pair of first and second coupling interfaces is provided, which form a positive connection and a pivot bearing.

The first coupling interface can be formed by an extension on the housing of the system, which is preferably formed in one piece with the housing. A housing of such a system can be produced, for example, by injection molding.

It is possible for several first coupling interfaces to be provided on the system, which are designed to interact with one or more transport handles that can be attached to the first coupling interfaces of the system.

The transport handles are preferably designed identically.

The housing-side coupling interface is formed in one piece on the housing and/or as a separate part to be attached to the housing.

The transport handle is non-destructive and can preferably be removed from the system without tools in order to be reused.

For example, the system is a vehicle air conditioning system, in particular an HVAC system.

In the 1 and 2 an assembly 10 with a system 12, which is intended for installation in a vehicle, and a transport handle 14 is shown in two different perspective views. The system 12 includes a housing 16 on which two first coupling interfaces 18 are provided. In the embodiment shown, the system 12 is a vehicle air conditioning system and is also referred to below as a vehicle air conditioning system 12, without this being limited to an air conditioning system. Correspondingly designed other systems 12 can be provided for installation in a vehicle for the assembly 10.

Two second coupling interfaces 20 are provided on the transport handle 14, which can be connected to the first coupling interfaces 18 of the vehicle air conditioning system 12 in order to attach the transport handle 14 to the vehicle air conditioning system 12.

Instead of two first and second coupling interfaces 18, 20, three or more interfaces 18, 20 or even just one first and second coupling interface 18, 20 can be provided, so that in the latter case the transport handle 14 may only be connected via one connection point Appendix 12 is fixed.

The vehicle air conditioning system 12 can be carried via the transport handle 14. The arrangement of the first coupling interfaces 18 and the design of the transport handle 14 can be selected so that the vehicle air conditioning system can be easily carried without affecting other functions or properties of the vehicle air conditioning system or causing plastic deformation of the housing.

After installing or removing the vehicle air conditioning system 12, the transport handle 14 can be dismantled non-destructively. In this way, the vehicle air conditioning system requires essentially no additional installation space when installed with the transport handle 14 removed. In the 3 and 4 The transport handle 14 is shown in the position decoupled from the vehicle air conditioning system 12.

The two first coupling interfaces 18 on the vehicle air conditioning system 12 are formed by fastening receptacles on the housing 16 of the vehicle air conditioning system 12, in which the second coupling interfaces 20 of the transport handle 14, which are designed as extensions, can be accommodated. A first and a second coupling interface 18, 20 each form a coupling interface pair.

A securing part 22 is provided, which is arranged in a securing position in such a way that the coupling interfaces 18, 20 are prevented from becoming loose. In the embodiment shown, the securing part 22 is a latching hook 24, which engages in a recess 26 of a coupling interface 18 on the housing 16 of the vehicle air conditioning system 12.

The transport handle 14 is in 5 shown. The two second coupling interfaces 20 are each designed as extensions. A first extension (seen on the left) is polygon-shaped and in this way forms a rotationally fixed, positive connection with the associated polygon-shaped coupling interface of the housing 16, which forms a negative shape for this purpose. The second extension (seen on the right) has a circular cross section and, together with the circular coupling interface 18 of the housing 16, forms a pivot bearing.

The design, in particular the shape and arrangement, of the coupling interfaces 18, 20 is essentially arbitrary and can be optimally adapted to the respective load according to the properties of the system 12 and the type of handling. The shape and arrangement of the coupling interfaces 18, 20 shown in the figures is just one exemplary embodiment from a large number of possible embodiments.

The coupling interfaces 18, 20 are preferably designed so differently that only a single fastening position of the transport handle 14 on the system 12 is possible. In this way, accidental incorrect attachment of the transport handle 14 to the system 12 can be prevented.

A simple positioning of the transport handle 14 on the housing 16 of the vehicle air conditioning system 12 is made possible by first connecting the coupling interfaces 18, 20 with a circular cross section to form the pivot bearing and then pivoting the transport handle about the axis of the pivot bearing until the two further coupling interfaces 18, 20 are positioned to each other. The lengths of the coupling interfaces 20 and the positions of the coupling interfaces 18 are preferably coordinated with one another in such a way that the parts having a circular cross-section are first inserted into one another before the others come into engagement with one another.

The one coupling interfaces form, so to speak, a guide for the other coupling interfaces included therein.

The first two coupling interfaces 18 are provided at different positions of the vehicle air conditioning system 12. The distance between the coupling interfaces 18 and the coupling interfaces 20 is at least half the length of the transport handle 14. In this way, the individual connections of the respective coupling interfaces 18, 20 that belong together are subject to less stress.

The transport handle 14 is in particular F- or P-shaped.

The securing part 22 can be used via an unlocking body 28 designed as a lever (see 6 ) can be moved to the unlocked position. It is also possible that the unlocking body 28 is part of a z. B. is an ejection mechanism designed with springs, which enables the coupling interfaces of the transport handle 14 and the vehicle air conditioning system 12 to be released.

The securing part can optionally be the only positive locking part in the pull-out direction of the transport handle 22. However, this is sufficient due to the guide receptacles of the handle in the coupling interfaces 18, to which a tilting movement is applied.

11 shows a detailed view of the first polygon-shaped extension of the transport handle 14, which forms one of the two second coupling interfaces 20. The securing part 22 is arranged in the form of a locking hook 24 on a surface of the polygon-shaped extension.

In the locked position, the locking hook 24 protrudes from the surface of the polygon-shaped extension and thus forms an undercut for the positive attachment of the transport handle 14 to the first coupling interface 18 on the housing 16 of the vehicle air conditioning system 12. The locking hook 24 is moved into its unlocked position by the unlocking body 28 moves, the locking hook 24 is retracted into the polygon-shaped extension of the transport handle and the positive connection is released.

The securing part 22 and/or the unlocking body 28 can also be arranged on the vehicle air conditioning system 12.

In the 7 and 8th are the first coupling interfaces designed as fastening receptacles len 18 of the housing 16 of the vehicle air conditioning system 12 shown in an exploded view.

The coupling interfaces 18 of the vehicle air conditioning system 12 can be formed in one piece on the housing 16 or can be formed by separate components (see 7 and 8th ), which are attached to the housing 16 or another component of the vehicle air conditioning system 12. The separate components can be made of a different material than the housing 16.

It is also possible for the first coupling interfaces 18 of the vehicle air conditioning system 12 to be attached to another component of the vehicle air conditioning system 12, with the transport handle 14 being able to extend, for example, partially through an opening in the housing 16 of the vehicle air conditioning system 12 into the interior of the housing 16.

9 shows the assembly 10 with a coupled transport handle 14 on the vehicle air conditioning system 12. In this position, the extensions of the second coupling interfaces 20 are accommodated in the fastening receptacles of the first coupling interfaces 18 on the housing 16 of the vehicle air conditioning system 12. A rotation of the transport handle 14 is prevented on the one hand by a polygonal cross section of a first pair of coupling interfaces and on the other hand by the interaction of the two pairs of coupling interfaces 18, 20.

A movement of the transport handle 14 in the axial direction is prevented on the one hand by the locking hook 24, which engages in the recess 26 of the first coupling interface 18, and on the other hand by a stop of the transport handle 14 on the housing 16 of the vehicle air conditioning system 12.

To decouple and remove the transport handle 14 from the vehicle air conditioning system 12, the unlocking body 28 is actuated, whereby the locking hook 24 is moved via a lever mechanism from the recess 26 in the fastening receptacle into an unlocked position.

Unintentional actuation of the unlocking body 28 or the locking hook 24 is prevented by the locking hook being biased into its securing position or by blocking movement of the unlocking body 28.

The locking hook 24 of the securing part 22 is in its unlocked position, as in 10 shown, the transport handle 14 can be moved out of the fastening receptacle on the housing 16 of the vehicle air conditioning system 12 in the axial direction.

As already mentioned, it is also possible for an ejection mechanism to be provided, with the transport handle 14 being completely or partially ejected from the fastening receptacle, for example by further actuation of the unlocking body 28.

In each of the figures shown, a section of the vehicle air conditioning system 12 is shown, to which a single transport handle 14 is attached. Further first coupling interfaces 18 are preferably provided on other sections of the vehicle air conditioning system 12, to which further transport handles 14 can be attached. In this case, the first coupling interfaces 18 on the vehicle air conditioning system 12 are preferably designed so that identical transport handles 14 can be used.

Different models of vehicle air conditioning systems 12 can each have identical first coupling interfaces 18, so that the same transport handle 14 can be used for different vehicle air conditioning systems 12.
